CD74HC595EG4

Shift Registers Overview

The CD74HC595EG4 is an 8-bit serial-in, parallel-out shift register manufactured by Texas Instruments. It belongs to the 74HC logic family and features 3-state output registers. The device operates within a supply voltage range of 2 V to 6 V and supports through-hole installation in a 16-pin PDIP package. It functions as a single circuit with rising-edge triggered data storage and unidirectional shifting capabilities.

Shift Registers Feature Summary

• Provides serial-to-parallel data conversion for expanding I/O capabilities
• Features 3-state outputs allowing direct bus connection
• Includes asynchronous reset functionality for immediate clearing

Shift Registers Applications

• LED display matrix scanning systems
• Industrial control panel indicator expansion
• General-purpose digital I/O port extension

Shift Registers Procurement Notes

Verify the specific suffix 'E' indicates the PDIP-16 through-hole package variant distinct from surface-mount options like DW or DB. Confirm RoHS compliance status via the official datasheet as manufacturing revisions may affect environmental declarations. Ensure the ordering part number matches the required pin configuration and thermal specifications for the target application environment.

Shift Registers Selection Notes

Select this component when through-hole mounting is required for the HC series 8-bit shift register architecture. Compare against SN74HC595 variants if surface-mount solutions are acceptable. Verify that the 2 V to 6 V operating voltage range aligns with the system power supply. Check package dimensions against PCB footprint constraints before finalizing the design.

Shift Registers Part Context

This part is a member of the Texas Instruments 74HC logic family, designed for high-speed CMOS operations. It shares functional compatibility with other 595-series devices but differs in physical packaging. The EG4 designation specifically identifies the lead-free PDIP-16 through-hole version, distinguishing it from SOIC or SSOP packages within the same logical product line.
